Title: Measles toxin and antitoxin and method of preparing the same
IPC: A61K39/165
Filed: 1927-03-08
Abstract: 267,520. Parke Davis &. Co., (Assignees of Ferry, N. S.). March 15, 1926, [Convention date]. Antitoxins, toxins, vaccines, and immunizing and like serums; bacteria, cultivating.-A microorganism (streptococcus morbilli) specific to measles is obtained by inoculating blood from a measles patient into a sterilized medium consisting of brain tissue and liver broth or liver infusion, transferring the culture obtained to whole-blood agar, and isolating streptococci only from those colonies producing a green halo. The organism is a Gram positive, aerobic streptococus, but may appear as a diplocoocus. Toxin is obtained by inoculating a medium such as 0.2 per cent glucose broth with a pure culture, and incubating for several days. Germ-free toxin may be obtained by filtration, or a toxin containing the living or killed organisms may be prepared. The toxin is standardized by means of the skin test, and may be employed for preventive immunization, for skin tests to determine susceptibility to measles, and for the production of antitoxin. An organism may be tested for identity with the specific measles streptococcus by determining the capacity of its sterile toxin, prepared in the above manner, to give characteristic skin reactions and to be neutralized in this respect by admixture with measles convalescent serum. Antitoxin is prepared by injecting a horse with increasing doses of toxin, whether germ-free or containing living or killed organisms, and concentrating, refining, and standardizing the serum.

Title: Process for the production of combustible gas enriched with methane
Inventor: DAVIS JOHN EDWARD
IPC: C10K3/02
Filed: 1953-03-09
Abstract: 798,741. Producing combustible gases. GAS COUNCIL. Aug. 13, 1954 [March 9, 1953], No. 6499/53. Class 55 (2). Gases containing carbon monoxide, hydrogen and methane are obtained by subjecting methanol vapour to the action of a catalyst or catalysts capable of promoting on the one hand the decomposition of methanol on to carbon monoxide and hydrogen and, on the other, the synthesis of methane from carbon monoxide and hydrogen, the temperature conditions being controlled to give a gas containing a desired proportion of methane to carbon monoxide and hydrogen. The methanol vapour may be passed in one stream over a catalyst or catalysts or as shown in Fig. 2, it may be passed over the catalysts in two streams, one stream over a catalyst promoting the decomposition reaction and the other stream over a catalyst promoting the synthesis reaction. Methanol vapour is produced in a boiler 1 and passes through a heat-exchanger 8 where it is heated by the gases leaving the reaction vessel 10. The methanol vapour is then split into two streams, one passing via line 19 through a bed of catalyst in vessel 10 to form a gas containing methane, while the other stream passes via line 18 through a catalytic mass contained in tubes 23 which are embedded in the catalytic mass in vessel 10 to produce a gas containing carbon monoxide and methane. The mixed gases pass out through the heat-exchanger 8, water condensing therein may be removed through pipe 16. The vessel 10 has an insulating jacket 12 and heat liberated by the reaction in the vessel 10 is sufficient to maintain the temperature for the reaction in the tubes 24. Initially the catalyst in vessel 10 is heated by passing a hot inert gas through the vessel. Suitable catalysts for the decomposition are alumina or zinc oxide and for the synthesis nickel or cobalt, a mixture of alumina and nickel is suitable for simultaneous promotion of both reactions. The temperature employed is somewhat above 300‹ C. and the methanol may be produced by synthesis from a mixture of carbon monoxide and hydrogen produced by the gasification of solid carbonaceous fuel.

Abstract: 878,666. Shovelling machines. McCONNEL Ltd., F. W., and ST. CLAIR CAMERON, C. April 29, 1960 [Feb. 26, 1959], No. 6786/59. Class 68(1). A tractor-mounted, ditch-digging and clearing apparatus comprises a boom 12 pivotally mounted about a fore and aft axis on the lift linkage of the tractor to extend sideways beyond the tractor and to be swingable upwards by a jack-actuated cable system 24 extending between the tractor and the boom. Pivoted at 14 at the free end of the boom is a bell crank lever 15, 27 having secured to the arm 15 a scoop-carrying structure and to the arm 27 a rod 29 having a spring detent 32 which co-operates with a latch member pivoted on a frame structure 35, 39 on the tractor. A stop 34 limits movement of the bell crank lever arm 15 in one direction towards the boom 12. The linkage relation of the boom, bell crank lever and rod 29 together with the detent control the movement of the scoop during a digging operation. With the detent engaging and the boom raised, freeing of the detent allows the bell crank to swing so that the scoop drops. Raising of the boom further then causes the scoop to continue to swing downwards towards the tractor to dig out a ditch and as the stop 34 engages the arm 15, further upward swinging of the boom causes re-engagement of the detent so that the scoop is swung clear of the ground. A spring and chain system causes automatic tipping of the scoop as it is raised clear of the ground.

Abstract: 630,713. Digesters. FABREGAT, M. P. March 14, 1947, No. 7138. Convention date, May 21, 1946. [Class 64(i)]  Vulcanized rubber to be devulcanized and regenerated in an autoclave having three independent heating means. viz., means for bringing the heating fluid into direct contact with the rubber, an internal tubular network 6, and an annular jacket 18 surrounding the cylindrical wall of the autoclave, is put into a drum 10, Fig. 5, which has internal vanes 40 and is carried into the autoclave on a carriage (not shown) running on rails 7, the drum being continuously rotated or set in intermittent alternating or oscillating movement from outside the autoclave. Complementary coupling members 5, 30 connect a power-driven shaft 4 to the drum shaft 29. The ends of the drum have gauzecovered apertures 36. Steam or other vapours, gases, or liquids from a pipe 56, Fig. 11, connected to the removable end 3 of the autoclave, passes through telescope tubes 57, 61 to a bore 62 which forks and leads to an annular chamber 68 which has a ring of outlets and an outlet passage 73. A masking member which fills the lower part of the chamber 68 and is weighted at the bottom and is free to move relatively to the shaft 29, closes the outlets which are below the level of the rubber in the drum, so that the steam then passes only into the space which is free of rubber. For sampling, the pipe assembly 56, 57, 61 and associated plug 55 are removed from the end plate 3 and replaced by a plug 45, Fig. 10, carrying a rotatable rod 46 with a dish 48 at its inner end. The dish is turned downwards until the time for sampling, when it is turned upwards and catches material which falls' from the drum wall after being carried, round by blades 40. A partition extends longitudinally through the jacket 18 between perforated inlet and outlet pipes 25 for saturated or superheated steam or other heating fluid. A vacuum can be produced in the autoclave. Pipes 15, 16, 17 communicate with the interior of the autoclave. Saturated or superheated steam is supplied through the pipe 15, and an air compressor and associated valves and branches are connected to the pipes 16, 17, so that air under pressure, or a mixture of air and vapours, can be supplied to the autoclave or circulated in closed circuit through the autoclave and compressor, or the autoclave be put under vacuum.
